White House Press Secretary Sean Spicer said at Thursday’s daily press briefing that he expects the Department of Justice will be “taking action” against states that have legalized recreational marijuana, and at the same time seemingly compared recreational use to the nationwide opioid crisis.

“There’s a big difference between [medical] and recreational marijuana,” Spicer said. “And I think that when you see something like the opioid addiction crisis blossoming in so many states around this country, the last thing that we should be doing is encouraging people.”

Spicer was addressing a question about medical marijuana from an Arkansas reporter. State voters legalized a medical marijuana program in the state last year.

“This president understands the pain and suffering that many people go through who are facing especially terminal diseases, and the comfort that some of these drugs, including medical marijuana, can bring them.”

But he added to the worry that some supporters of recreational marijuana have had since Jeff Sessions, who has in the past been a critic of legal recreational pot, was nominated and confirmed as the new U.S. attorney general.
